Question

a block of wood has a density of 0.95 g/cm3. will it float or sink when placed on a liquid with a density of 0.88 g/mL? explain your answer.

Answer 1

Since 1mL=1cm^3 the wood would sink due to it being more dense. I.e. 0.95>0.88

Answer 2

Answer : The block of wood will sink.

Explanation :

As we given that:

The density of block of wood = $0.95g/cm^3=0.95g/mL$

The density of liquid = 0.88 g/mL

• When the density of a substance will be greater than the density of medium then the substance will sink.
• When the density of a substance will be lesser than the density of medium then the substance will float.

As per question we conclude that,

The density of substance (wood) is greater than the density of medium (liquid). That means, the block of wood will sink.

Hence, the block of wood will sink.
